December is the peak of the wet season in Vanuatu. Rain becomes more frequent, with about 15 days of rainfall throughout the month. While showers can be intense at times, they are usually short-lived, leaving plenty of time to enjoy sunny spells between downpours.

December falls within the official South Pacific cyclone season, which runs from November to April. While cyclones in Vanuatu are not guaranteed each year, the risk rises during this period due to warmer seas and humid tropical air.

Historically, Vanuatu has experienced several impactful cyclones in December, with strong winds, heavy rainfall, and occasional disruption to local infrastructure.

While direct hits are rare, it's wise to monitor local advisories and familiarise yourself with Cyclone Safety in Vanuatu.

If you're visiting Vanuatu in December, it’s wise to have travel insurance and a flexible itinerary, just in case a tropical cyclone develops during your trip.

December can be one of the busier months in Vanuatu, but the warm tropical weather and festive events make the islands especially inviting.

As the main hub, Efate and Port Vila are lively in December, with local Christmas celebrations, markets, and community events. It’s a great time to explore beaches, enjoy coastal hikes, or soak in the city’s vibrant culture while still finding peaceful spots along the shore.

See what Port Vila and Efate has to offer in our 30 Best Things to Do in Port Vila & Efate.

For a more secluded escape, islands like Tanna LINK#D071 and Espiritu Santo LINK#D053 offer quiet beaches, pristine coral reefs, and a chance to immerse yourself in authentic island life. These islands are perfect for travellers seeking relaxation away from the festive buzz of the main centres.
